[Gmecm] Reprograming ECM from CPI to TBI

[Tom Butcher]

You can "reprogram" the 16168625 to go from a 4.3 CPI to a 5.7 TBI just by getting a new Memcal for the 5.7 TBI and tranny and gears you are running.  You may have to switch to a truck Memcal to get a good match.  HTH

can I reprogram the 16168625 to run TBI(I know that I will have to add 
another "twisted pair")or will I have to replace the whole system with a
